The SI unit of electric field intensity is

Options

A. `N`
B. `N//C`
C. `C//m^(2)`
D. `N//m^(2)`

Explanation

To find the SI unit of electric field intensity, we can follow these steps:

### Step 1: Understand Electric Field Intensity
Electric field intensity (E) is defined as the force (F) experienced by a test charge (q) placed in the electric field.

### Step 2: Write the Formula
The formula for electric field intensity can be expressed as:
\[ E = \frac{F}{q} \]
where:
- \( E \) is the electric field intensity,
- \( F \) is the force experienced by the charge,
- \( q \) is the magnitude of the charge.

### Step 3: Identify the Units
- The SI unit of force (F) is Newton (N).
- The SI unit of electric charge (q) is Coulomb (C).

### Step 4: Substitute the Units into the Formula
Now, substituting the units into the formula for electric field intensity:
\[ E = \frac{N}{C} \]
Thus, the SI unit of electric field intensity is Newton per Coulomb.

### Step 5: Conclusion
Therefore, the SI unit of electric field intensity is:
\[ \text{Newton per Coulomb (N/C)} \]

### Final Answer
The SI unit of electric field intensity is Newton per Coulomb (N/C).
